? is this a silky mix?

I got this little one named Trouble with the rest of the "silky chicks" she has a black beak, black legs n feet 5 toes, but she is the only one who's feathers are growing in looking normal and the other 4 have feathers that look more like hair after the pin sheath comes off. The chick is only a week, I'm just curious if anyone else thinks the normal feather may mean a silky cross of some sort. Either way we love Trouble as she is (she- fingers crossed)

Thanks, I figured it was prob too early to tell, this is our first batch of chickens ever, so it is ALL an adventure. Trouble just looks a little different than the others. We don't plan on telling her though!
